Birds: Feathers, Beaks and Claws

A Today you'll learn

Explain how birds fly using hollow bones, wings, and specialized feathers
Identify different types of beaks and connect them to birds’ feeding habits
Understand how different claws help birds perch, swim, climb, or catch prey

B Let's understand

Birds are warm-blooded vertebrates covered with feathers. They have lightweight, hollow bones and streamlined bodies that enable them to fly easily through the air. Birds have three types of feathers: flight feathers on wings and tails for flying and steering, down feathers close to the skin to keep warm, and body feathers that give shape. Birds do not have teeth; instead, they have beaks designed specifically for their diet. A sparrow has a short, cone-shaped beak for crushing seeds; an eagle has a sharp, hooked beak for tearing meat; and a woodpecker has a strong, chisel-shaped beak for drilling into tree bark for insects. Their claws and feet are equally specialized for perching, swimming, scratching, or grasping.

C See it step by step

Example 1: Why can birds fly while dogs and cats cannot?

Birds have light, hollow bones filled with air cavities that reduce body weight.
They possess strong chest muscles and streamlined, boat-shaped bodies.
Their forelimbs are modified into wings covered with aerodynamic feathers.

Example 2: How does a duck’s beak differ from an eagle’s beak?

Duck: Broad, flat beak with tiny strainer holes on the sides to filter water and mud while catching aquatic plants and insects.
Eagle: Strong, sharp, hooked beak designed for gripping and tearing flesh from prey.

D Your turn

Which feathers keep a bird warm by trapping body heat?

Look back at "Let's understand" above for a clue.

E Ready to practise?

Birds have hollow bones

Birds have hollow bones, powerful chest muscles, and wings that allow flight.

Key idea 2

Flight feathers help in flying; down feathers keep the bird warm.

Key idea 3

Birds do not have teeth; their beaks are adapted to the food they eat.

Key idea 4

Ducks have webbed feet to paddle through water like flippers.

Eagles and hawks have sharp

Eagles and hawks have sharp, curved talons to catch and grasp prey.
